Logs

which is the LOG SERVER requirement for the 27001 firewall ?
 

Answer:

I am not sure what you mean, but there is not specific requirement in ISO 27001 related to log firewalls, although you can find the control objective “A.12.4 Logging and monitoring”, which has controls for event logging, protection of logs, clock synchronization and administrator and operator logs. So there are requirements in the standard related to any type of logs.
